Perfect Alignment for Steel and Aluminium Mills at Siemens with FARO devices

Rolling mill machines can be many stories high and include components weighing hundreds of tonnes. But using FARO tools, Siemens Metals Technologies plant makers still achieve sub-millimetre levels of accuracy.

Siemens Metals Technologies’ expertise in rolling mills dates back to 1830 when the company Davy Brothers was founded in Sheffield, England. By 1914, the company was specialised in steel works plant and machinery. A merger with an American counterpart in 1937 led to Davy-United Engineering whose principal activity was manufacturing rolling mills and related equipment. Today, Siemens Metals Technologies offers a complete range of technologies, plants & services covering the entire life cycle in the metallurgical industry to customers all over the world.

“A typical modern steel plant has an output of about 450 tonnes per hour. Interrupting production for inspection or alignment is very costly, so we need to work very fast,” explains Craig Flower, Design Engineer in the Metal Services Dept. of Siemens Metals Technologies in Sheffield.

“When we began considering our options for 3D measuring devices, one of our team suggested we look at FARO. We saw the equipment demonstrated at the Sheffield Arena Expo and FARO also gave us an on-site demonstration. We started off with a FaroArm® Platinum in 2008 and added a FARO Laser Tracker ION® in July 2011.”

Both devices have been used for inspection and alignment jobs all over the UK. For example: Steel plates coming off a mill need to be trimmed using a double-sided shear with perfectly parrallel blades: We had an alignment job where the blades were very difficult to access. Using conventional methods, the measurements and alignment would have taken several days. Using the FARO ION, it took less than one day,” smiles Craig Flower.

Another case where conventional methods can be tricky is when perpendicular alignments are required: in aluminium mills, the downcoiler needs to be exactly 90° to the aluminium sheets. Working conventionally with a theodilite, is much harder than doing the same job with a tracker.

“We were recently measuring the housing windows of a large steel plate mill”. The housing windows hold the roll chocks for the bearings and they are typically over 2 metres apart. The traditional approach – using stick micrometres is prone to error as most sticks will sag and be inaccurate over such distances. “The ION on the other hand allows us to very easily measure these distance to extremely high accuracies.”

Siemens is a global technology leader, so our customer’s really expect us to have state-of-the-art solutions. The combination of FARO hardware and software is a great productivity boost. The measurements are easily exported from CAM2 Measure 10 software to Excel for comparison, to CAD software for reverse engineering or as a PDF report for our customers.”

“All in all, FARO devices us to satisfy our customer’s expectations!”
